摘要： An image intensifier tube includes a microchannel plate (MCP) (94) having conductive input and output surfaces disposed in a housing. A conductive lower support (92) is in electrical contact with the output surface of the MCP, and a conductive upper support (91) is disposed above the input surface of the MCP. A shape memory alloy (SMA) lockdown (93,96) is disposed between the input surface of the MCP and the upper support. The SMA lockdown is configured to provide a lockdown for the MCP in the housing. An SMA upper surface (93A,96A) is configured to provide an axial force against the upper support, and an SMA lower surface (93C,96C) is in contact with the input surface of the MCP.
